DETAILED DESCRIPTION

Conventionally, when recording a television program on a television channel, a television receiver may use a tuner to receive a stream of data at a particular frequency that contains the television channel. Data associated with the television program may then be stored for playback via a display device at a later time. In such conventional arrangements, for each television channel that is recorded, a tuner of the television receiver may be used to receive the stream of data containing the television channel. As such, in a conventional arrangement, the number of television channels recorded concurrently by the television receiver may be greatly restricted. For example, if a television receiver has three tuners, only three different television channels may be recorded at the same time (and/or one or more of these three different television channels may be output for presentation to a display device, such as a television).

In contrast to such conventional arrangements, it may be possible to use a single tuner to receive multiple television channels for recording (and/or presentation) concurrently using a single tuner. Multiple television channels that are transmitted as part of the same data stream (which may be in the form of a transponder stream) may be received using a single tuner. As such, if multiple television channels that a user desires to record are transmitted as part of a same transponder stream, a single tuner of a television receiver may be used to receive the multiple television channels for recording. Therefore, fewer resources of the television receiver may need to be devoted to recording television programs if the television programs are transmitted as parts of the same transponder stream.

Which television channels are assigned to which transponder stream may be decided by the television service provider. As such, a user may have no obvious way of determining which television channels are transmitted as part of the same transponder stream (and thus can be received concurrently using a single tuner of the television receiver). Concurrently receiving multiple television channels may involve a broadcast of the television channels being received over a same period of time. Embodiments detailed herein provide a user with on-screen options for selecting television channels to record via a single tuner.

In some embodiments, a user is presented with an option to select among predefined television channel groups. Each group may contain television channels transmitted to the television receiver as part of a single transponder stream. As such, for each group of television channels to be recorded concurrently, only a single tuner of the television receiver may need to be used. For each group, the specific television channels and/or the date/times at which the television channels within the group are recorded may be defined by the television service provider. In some embodiments, a user may define the record date/times for each group of the television channels.

In some embodiments, a user may be permitted to use an electronic programming guide (EPG) to select a television program for recording. The television receiver may determine which other television channels are also available for recording using the same transponder. The user may then be presented with an on-screen selection indicating one or more other television channels which can be recorded concurrently using a single tuner. The record times of such other television channels may be adjusted such that recording on each of these other television channels begins at a start of a television program and ends at an end of a television program.

FIG. 1 illustrates an embodiment of a satellite television distribution system 100. While embodiments detailed herein may be applied to various television distribution systems, including cable and IP, a satellite television distribution system is provided as an example. Satellite television distribution system 100 may include: television service provider system 110, satellite transmitter equipment 120, satellites 130, satellite dish 140, television receiver 150, and television 160. Alternate embodiments of satellite television distribution system 100 may include fewer or greater numbers of components. While only one satellite dish 140, television receiver 150, and television 160 (collectively referred to as “user equipment”) are illustrated, it should be understood that multiple (e.g., tens, thousands, millions) instances of user equipment may receive television signals from satellites 130.

Television service provider system 110 and satellite transmitter equipment 120 may be operated by a television service provider. A television service provider may distribute television channels, on-demand programming, programming information, and/or other services to users. Television service provider system 110 may receive feeds of one or more television channels from various sources. Such television channels may include multiple television channels that contain the same content (but may be in different formats, such as high-definition and standard-definition). To distribute such television channels to users, feeds of the television channels may be relayed to user equipment via one or more satellites via transponder streams. Satellite transmitter equipment 120 may be used to transmit a feed of one or more television channels from television service provider system 110 to one or more satellites 130. While a single television service provider system 110 and satellite transmitter equipment 120 are illustrated as part of satellite television distribution system 100, it should be understood that multiple instances of transmitter equipment may be used, possibly scattered geographically to communicate with satellites 130. Such multiple instances of satellite transmitting equipment may communicate with the same or with different satellites. Different television channels may be transmitted to satellites 130 from different instances of transmitting equipment. For instance, a different satellite dish of satellite transmitter equipment 120 may be used for communication with satellites in different orbital slots.

Satellites 130 may be configured to receive signals, such as streams of television channels, from one or more satellite uplinks such as satellite transmitter equipment 120. Satellites 130 may relay received signals from satellite transmitter equipment 120 (and/or other satellite transmitter equipment) to multiple instances of user equipment via transponder streams. Different frequencies may be used for uplink signals 170 from transponder stream 180. Satellites 130 may be in geosynchronous orbit. Each satellite 130 may be in a different orbital slot, such that the signal paths between each satellite, transmitter equipment, and user equipment vary. Each satellite 130 may have multiple transponders operating at different transmit frequencies. Multiple satellites 130 may be used to relay television channels from television service provider system 110 to satellite dish 140. Different television channels may be carried using different satellites and/or different transponders. Different television channels may also be carried using different transponders of the same satellite; thus, such television channels may be transmitted at different frequencies and/or different frequency ranges. As an example, a first and second television channel may be carried on a first transponder of satellite 130-1 (and thus be part of a first transponder stream). A third, fourth, and fifth television channel may be carried using a different satellite or a different transponder of the same satellite relaying the transponder stream at a different frequency (and thus be part of a second transponder stream). A transponder stream transmitted by a particular transponder of a particular satellite may include a finite number of television channels, such as seven. Accordingly, if many television channels are to be made available for viewing and recording, multiple transponder streams may be necessary to transmit all of the television channels to the instances of user equipment.

Satellite dish 140 may be a piece of user equipment that is used to receive transponder streams from one or more satellites, such as satellites 130. Satellite dish 140 may be provided to a user for use on a subscription basis to receive television channels provided by the television service provider system 110, satellite transmitter equipment 120, and/or satellites 130. Satellite dish 140 may be configured to relay transponder streams from multiple satellites and/or multiple transponders of the same satellite to television receiver 150. Based on the characteristics of television receiver 150 and/or satellite dish 140, it may only be possible to capture transponder streams from a limited number of transponders concurrently. For example, a tuner of television receiver 150 may only be able to tune to a single transponder stream from a transponder of a single satellite at a time.

In communication with satellite dish 140 may be one or more sets of receiving equipment. Receiving equipment may be configured to decode signals received from satellites 130 via satellite dish 140 for display on a display device, such as television 160. Receiving equipment may be incorporated as part of a television or may be part of a separate device, commonly referred to as a set-top box (STB). Receiving equipment may include a satellite tuner configured to receive television channels via a satellite. In FIG. 1, receiving equipment is present in the form of television receiver 150. As such, television receiver 150 may decode signals received via satellite dish 140 and provide an output to television 160. FIG. 2 provides additional detail of a television receiver. A television receiver is defined to include set-top boxes (STBs) and also circuitry having similar functionality that may be incorporated with another device. For instance, circuitry similar to that of television receiver 150 may be incorporated into a television. As such, while FIG. 1 illustrates an embodiment of television receiver 150 as separate from television 160, it should be understood that in other embodiments, similar functionality may be present in a television receiver integrated with television 160.

Television 160 may be used to present video and/or audio decoded by television receiver 150. Television receiver 150 may also output a display of one or more interfaces to television 160, such as an electronic programming guide (EPG). In some embodiments, a display device other than a television may be used.

Uplink signal 170-1 represents a signal between satellite transmitter equipment 120 and satellite 130-1. Uplink signal 170-2 represents a signal between satellite transmitter equipment 120 and satellite 130-2. Each of uplink signals 170 may contain streams of one or more different television channels. For example, uplink signal 170-1 may contain a certain group of television channels, while uplink signal 170-2 contains a different grouping of television channels. Each of these television channels may be scrambled such that unauthorized persons are prevented from accessing the television channels.

Transponder stream 180-1 represents a signal between satellite 130-1 and satellite dish 140. Transponder stream 180-2 represents a signal between satellite 130-2 and satellite dish 140. Each of transponder streams 180 may contain one or more different television channels in the form of transponder streams, which may be at least partially scrambled. For example, transponder stream 180-1 may include a first transponder stream containing a first group of television channels, while transponder stream 180-2 may include a second transponder stream containing a different group of television channels. A satellite may transmit multiple transponder streams to user equipment. For example, a typical satellite may relay thirty-two transponder streams via thirty-two transponders to user equipment. Further, spot beams are possible. For example, a satellite may be able to transmit a transponder stream to a particular geographic region (e.g., to distribute local television channels to the relevant market). Different television channels may be transmitted using the same frequency of the transponder stream to a different geographic region.

FIG. 1 illustrates transponder stream 180-1 and transponder stream 180-2 being received by satellite dish 140. For a first group of television channels, satellite dish 140 may receive a transponder stream of transponder stream 180-1; for a second group of channels, a transponder stream of transponder stream 180-2 may be received. Television receiver 150 may decode the received transponder stream. As such, depending on which television channel(s) are desired, a transponder stream from a different satellite (or a different transponder of the same satellite) may be accessed and decoded by television receiver 150. Further, while two satellites are present in satellite television distribution system 100, in other embodiments greater or fewer numbers of satellites may be present for receiving and transmitting transponder streams to user equipment.

Network 190 may serve as a secondary communication channel between television service provider system 110 and television receiver 150. Via such a secondary communication channel, bidirectional exchange of data may occur. As such, data may be transmitted to television service provider system 110 via network 190. Data may also be transmitted from television service provider system 110 to television receiver 150 via network 190. Network 190 may be the Internet. While audio and video services may be provided to television receiver 150 via satellites 130, feedback from television receiver 150 to television service provider system 110 may be transmitted via network 190.

FIG. 1 illustrates an example of a satellite-based television channel distribution system. It should be understood that at least some of the aspects of such a system may be similar to a cable television distribution system. For example, in a cable television system, rather than using satellite transponders, multiple RF channels on a cable may be used to transmit streams of television channels. As such, aspects detailed herein may be applicable to cable television distribution systems.

FIG. 2 illustrates an embodiment of television receiver 200, which may typically be in the form of a separate device configured to be connected with a presentation device, such as a television. Embodiments of television receiver 200 may include set top boxes (STBs). As previously noted, in addition to being in the form of an STB, a television receiver may be incorporated into another device, such as a television. For example, a television may have an integrated television receiver (which does not involve an external STB being coupled with the television). An STB may contain some or all of the components of television receiver 200 and/or may be able to perform some or all of the functions of television receiver 200. Accordingly, instances in this document referring to an STB and steps being performed by an STB may also be performed, more generally, by a television receiver.

FIG. 2 illustrates a block diagram of an embodiment of television receiver 200 that is configured to record omnibus channel files and extract a television program from a recorded omnibus channel file. Television receiver 200 may be television receiver of FIG. 1 and may be in the form of an STB that communicates with a display device such as a television. Television receiver 200 may be incorporated as part of a television, such as television 160 of FIG. 1. Television receiver 200 may include: processors 210 (which may include control processor 210-1 and tuning management processor 210-2), tuners 215, network interface 220, non-transitory computer-readable storage medium 225, electronic programming guide (EPG) database 230, television interface 235, networking information table (NIT) 240, group database 244, digital video recorder (DVR) database 245, user interface 250, PID filters 255, smart card 260, and/or descrambling engine 265. In other embodiments of television receiver 200, fewer or greater numbers of components may be present. It should be understood that the various components of television receiver 200 may be implemented using hardware, firmware, software, and/or some combination thereof. Functionality of components may be combined; for example, functions of descrambling engine 265 may be performed by tuning management processor 210-2. Further, functionality of components may be spread among additional components; for example, PID filters 255 may be handled by separate hardware from program management table 257.

Processors 210 may include one or more specialized and/or general-purpose processors configured to perform processes such as tuning to a particular channel, accessing and causing EPG information from EPG database 230 to be displayed, and/or receiving and processing input from a user. For example, processors 210 may include one or more processors dedicated to decoding video signals from a particular format, such as MPEG, for output and display on a television and for performing decryption. It should be understood that the functions performed by various modules of FIG. 2 may be performed using one or more processors. As such, for example, functions of descrambling engine 265 may be performed by control processor 210-1.

Control processor 210-1 may communicate with tuning management processor 210-2. Control processor 210-1 may control the recording of television channels based on timers stored in DVR database 245. Control processor 210-1 may initiate recording of a television channel by sending a record command along with an indication of the television channel to be recorded to tuning management processor 210-2. Control processor 210-1 may not send a second record command (if additional recording is to begin at the same time) until an acknowledgement that recording of the first television channel has successfully been received and initiated by tuning management processor 210-2. Control processor 210-1 may also provide commands to tuning management processor 210-2 when recording of a television channel is to cease. In addition to providing commands relating to the recording of television channels, control processor 210-1 may provide commands to tuning management processor 210-2 that indicate television channels to be output to audio/video decoder 233 for output to a presentation device, such as a television.

Control processor 210-1 may also communicate with network interface 220 and user interface 250. Control processor 210-1 may handle incoming data from network interface 220 and user interface 250. Additionally, control processor 210-1 may be configured to output data via network interface 220.

Tuners 215 may include one or more tuners used to tune to television channels, such as television channels transmitted via satellite or cable. In the illustrated embodiment of television receiver 200, three tuners are present (tuner 215-1, tuner 215-2, and tuner 215-3). Each tuner contained in tuners 215 may be capable of receiving and processing a single stream of data from a satellite transponder (or a cable RF channel) at a given time. As such, a single tuner may tune to a single transponder (or, for a cable network, a single cable RF channel). If tuners 215 include multiple tuners, one tuner may be used to tune to a television channel on a first transponder stream for display using a television, while another tuner may be used to tune to a television channel on a second transponder for recording and viewing at some other time. Still another tuner may be used to check various television channels to determine if they are available or not. If multiple television channels transmitted on the same transponder stream are desired, a single tuner of tuners 215 may be used to receive the signal containing the multiple television channels for presentation and/or recording. Tuners 215 may receive commands from tuning management processor 210-2. Such commands may instruct tuners 215 which frequencies are to be used for tuning. Tuning management processor 210-2 may access network information table 240 and/or program management table 257 to determine a correct transponder stream (a correct satellite and transponder) to which to tune to receive a desired television channel.

Network interface 220 may be used to communicate via an alternate communication channel with a television service provider. For example, the primary communication channel may be via satellite (which may be unidirectional to the STB) and the alternate communication channel (which may be bidirectional) may be via a network, such as the Internet. Referring back to FIG. 1, television receiver 150 may be able to communicate with television service provider system 110 via a network, such as the Internet. This communication may be bidirectional: data may be transmitted from television receiver 150 to television service provider system 110 and from television service provider system 110 to television receiver 150. Referring back to FIG. 2, network interface 220 may be configured to communicate via one or more networks, such as the Internet, to communicate with television service provider system 110 of FIG. 1. Information may be transmitted and/or received via network interface 220.

Storage medium 225 may represent a non-transitory computer-readable storage medium. Storage medium 225 may include memory and/or a hard drive. Storage medium 225 may be used to store information received from one or more satellites and/or information received via network interface 220. Storage medium 225 may store information related to EPG database 230, NIT 240 (rather than being stored locally by tuning management processor 210-2), and/or DVR database 245. Recorded television programs may be stored using storage medium 225.

EPG database 230 may store information related to television channels and the timing of programs appearing on such television channels. EPG database 230 may be stored using storage medium 225, which may be a hard drive. Information from EPG database 230 may be used to inform users of what television channels or programs are popular and/or provide recommendations to the user. Information from EPG database 230 may provide the user with a visual interface displayed by a television (or other form of display device) that allows a user to browse and select television channels and/or television programs for viewing and/or recording. Information used to populate EPG database 230 may be received via network interface 220 and/or via satellites, such as satellites 130 of FIG. 1 via tuners 215. For instance, updates to EPG database 230 may be received periodically via satellite. Data from EPG database 230 may be used to present an interface for a user to control DVR functions of television receiver 200, and/or to enable viewing and/or recording of multiple television channels simultaneously.

In addition to being used to provide users with information about scheduled programming, information from EPG database 230 may be used to determine when television programs begin and end for the purposes of recording. For instance, if a channel-specific file is recorded that contains multiple television programs, the start and end of time of specific television programs within the channel-specific file may be based on the start and end times indicated in the EPG. Other data may be stored for the EPG that may be useful in managing channel-specific files, such as series identifiers and episode identifiers (which may be used by a television service provider to identify particular television programs).

Audio/video decoder 233 may serve to convert encoded video and audio into a format suitable for output to a display device. For instance, audio/video decoder 233 may receive MPEG video and audio from storage medium 225 or descrambling engine 265 to be output to a television. MPEG video and audio from storage medium 224 may have been recorded to DVR database 245 as part of a previously-recorded television program. Audio/video decoder 233 may convert the MPEG video and audio into a format appropriate to be displayed by a television or other form of display device and audio into a format appropriate to be output from speakers, respectively.

Television interface 235 may serve to output a signal to a television (or another form of display device) in a proper format for display of video and playback of audio. As such, television interface 235 may output one or more television channels and stored television programming from storage medium 225 (e.g., television programs from DVR database 245 and/or information from EPG database 230) to a television for presentation.

The Network Information Table (NIT) 240 may store information used by television receiver 200 to access various television channels. NIT 240 may be stored locally by a processor, such as by tuning management processor 210-2. Information used to populate NIT 240 may be received via satellite (or cable) through tuners 215 and/or may be received via network interface 220 from the television service provider. As such, information present in NIT 240 may be periodically updated. In some embodiments, NIT 240 may be locally-stored by television receiver 200 using storage medium 225. Generally, NIT 240 may store information about a service provider network, such as a satellite-based service provider network. Information that may be present in NIT 240 may include: television channel numbers, satellite identifiers, frequency identifiers and/or transponder identifiers for various television channels. In some embodiments, NIT 240 may contain additional data or additional tables may be stored by the television receiver. For example, specific audio PIDs and video PIDs may not be present in NIT 240, a channel identifier may be present within NIT 240 which may be used to look up the audio PIDs and video PIDs in another table, such as a program map table (PMT). In some embodiments, a PID associated with the data for the PMT is indicated in a separate table, program association table (PAT), which is not illustrated in FIG. 2. A PAT may be stored by the television receiver in a similar manner to the NIT. For example, a PMT may store information on audio PIDs, video PIDs, and/or ECM (entitlement control message) PIDs for television channels that are transmitted on a transponder frequency.

Table 1 provides a simplified example of NIT 240 for several television channels. It should be understood that in other embodiments, many more television channels may be represented in NIT 240. NIT 240 may be periodically updated by a television service provider. As such, television channels may be reassigned to different satellites and/or transponders, and television receiver 200 may be able to handle this reassignment as long as NIT 240 is updated.

TABLE 1 Channel Satellite Transponder 4 1 2 5 2 11 7 2 3 13 2 4

Based on information in the NIT, it may be possible to determine the proper satellite and transponder to which to tune for a particular television channel. In some embodiments, the NIT may list a particular frequency to which to tune for a particular television channel. Once tuned to the proper satellite/transponder/frequency, a known PMT PID may be used to retrieve a program map table that indicates the PIDs for audio and video streams of television channels transmitted by that transponder.

It should be understood that the values provided in Table 1 are for example purposes only. Actual values, including how satellites and transponders are identified, may vary. Additional information may also be stored in NIT 240. Additional information on how NIT 240, as indicated in Table 1, may be used is provided in reference to FIG. 3. The same PID may be reused on different transponders.

A Digital Video Recorder (DVR) device may permit a television channel to be recorded for a period of time. DVR functionality of television receiver 200 may be managed by control processor 210-1. Control processor 210-1 may coordinate the television channel, start time, and stop time of when recording of a television channel is to occur. DVR database 245 may store information related to the recording of television stations. DVR database 245 may store timers that are used by control processor 210-1 to determine when a television channel should be tuned to and recorded to DVR database 245 of storage medium 225. In some embodiments, a limited amount of storage medium 225 may be devoted to DVR database 245. Timers may be set by the television service provider and/or one or more users of television receiver 200.

The DVR functionality of control processor 210-1 may have multiple modes. First, the DVR functionality of control processor 210-1 may be configured to record individual television programs selected by a user to DVR database 245. Using EPG database 230, a user may select a particular television program. Based on the date, time period, and television channel indicated by EPG database 230, Control processor 210-1 may record the associated television program to DVR database 245. Second, DVR database 245 may be used to store recordings of predefined periods of time on one or more television channels defined by a television service provider. These predefined periods of time may include one or more television programs. For example, primetime programming on a particular television network may be recorded each weekday night. Further, multiple television channels may be recorded for such predefined periods of time. Such recording of television channels for predefined periods of time may be defined by the television service provider.

As an example of this second mode of DVR functionality, a television service provider may configure television receiver 200 to record television programming on multiple, predefined television channels for a predefined period of time, on predefined dates. For instance, a television service provider may configure television receiver 200 such that television programming may be recorded from 7 to 10 PM on NBC, ABC, CBS, and FOX on each weeknight. If a television program is selected for recording by a user and is also specified for recording by the television service provider, the user selection may serve as an indication to save the television program for an extended time (beyond the time which the predefined recording would otherwise be saved).

Further, DVR functionality may include control processor 210-1, or some other processing device of television receive 200, determining multiple television channels that can be recorded simultaneously using a single tuner to receive the multiple television channels. For example, a user may select a particular television program that is to be broadcast on a particular television channel for recording. Based on the television channel selected, control processor 210-1 may access a database, such as group database 244, to determine one or more additional television channels that are transmitted as part of the same transponder stream. In some embodiments, rather than consulting group database 244 to determine which television channels can be received concurrently using a single tuner, control processor 210-1 may examine NIT 240 (or some other data storage arrangement) to identify other television channels associated with the same frequency and/or satellite and transponder.

Group database 244 may store data indicating groups of television channels transmitted using a same transponder stream. As such, each group identified within group database 244 may be received concurrently using a single tuner. The groupings of television channels stored by group database 244 may be transmitted to television receiver 200 by the television service provider. In some embodiments, by analyzing NIT 240 and/or PMT 257, control processor 210-1 may identify the groupings of television channels and store them to group database 244. In some embodiments, rather than constructing group database 244, control processor 210-1 (or some other processing device) may analyze data present in NIT 240, PMT 257, and/or some other data storage arrangement to determine television channels transmitted as part of a same transponder stream.

User interface 250 may include a remote control (physically separate from television receiver 200) and/or one or more buttons on television receiver 200 that allow a user to interact with television receiver 200. User interface 250 may be used to select a television channel for viewing, view information from EPG database 230, and/or program a timer stored to DVR database 245, wherein the timer is used to control the DVR functionality of control processor 210-1.

Referring back to tuners 215, television channels received via satellite (or cable) may contain at least some scrambled data. Packets of audio and video may be scrambled to prevent unauthorized users (e.g., nonsubscribers) from receiving television programming without paying the television service provider. When a tuner of tuners 215 is receiving data from a particular transponder of a satellite, the transponder stream may be a series of data packets corresponding to multiple television channels. Each data packet may contain a packet identifier (PID), which, in combination with NIT 240 and/or PMT 257, can be determined to be associated with a particular television channel. Particular data packets, referred to as entitlement control messages (ECMs), may be periodically transmitted. ECMs may be associated with another PID and may be encrypted; television receiver 200 may use smart card 260 to decrypt ECMs. Decryption of an ECM may only be possible if the user has authorization to access the particular television channel associated with the ECM. When an ECM is determined to correspond to a television channel being stored and/or displayed, the ECM may be provided to smart card 260 for decryption.

When smart card 260 receives an encrypted ECM, smart card 260 may decrypt the ECM to obtain some number of control words. In some embodiments, from each ECM received by smart card 260, two control words are obtained. In some embodiments, when smart card 260 receives an ECM, it compares the ECM to the previously received ECM. If the two ECMs match, the second ECM is not decrypted because the same control words would be obtained. In other embodiments, each ECM received by smart card 260 is decrypted; however, if a second ECM matches a first ECM, the outputted control words will match; thus, effectively, the second ECM does not affect the control words output by smart card 260. Smart card 260 may be permanently part of television receiver 200 or may be configured to be inserted and removed from television receiver 200.

Tuning management processor 210-2 may be in communication with tuners 215 and control processor 210-1. Tuning management processor 210-2 may be configured to receive commands from control processor 210-1. Such commands may indicate when to start/stop recording of a television channel and/or when to start/stop causing a television channel to be output to a television. Tuning management processor 210-2 may control tuners 215. Tuning management processor 210-2 may provide commands to tuners 215 that instruct the tuners which satellite, transponder, and/or frequency to which to tune. From tuners 215, tuning management processor 210-2 may receive transponder streams of packetized data. As previously detailed, some or all of these packets may include a PID that identifies the content of the packet.

Tuning management processor 210-2 may be configured to create one or more PID filters 255 that sort packets received from tuners 215 based on the PIDs. When a tuner is initially tuned to a particular frequency (e.g., to a particular transponder of a satellite) a PID filter may be created based on a PID of PMT data. The PID of PMT data packets may be known because it is stored as part of NIT 240 or another table, such as a PAT. From the PMT data packets, PMT may be constructed by tuning management processor 210-2. Table 2 provides an exemplary extract of a PMT. PMT 257 may be specific to a particular transponder. As such, if tuning to a different transponder occurs, a new PMT may be created for the different transponder.

TABLE 2 1^(st) Audio 2^(nd) Audio Channel Video PID PID PID 4 1003 2383 2119 5 2993 2727 2728 7 9238 1233 0129 13 0012 9348 —

Accordingly, based on the information present in PMT 257, the audio and video PIDs for specific television channels may be identified. A television channel may have multiple audio PIDs due to a second audio program (SAP), which may be in a different language.

It should be understood that the values provided in Table 2 are for example purposes only. Actual values may vary. Additional information or less information may also be stored in PMT 257.

PID filters 255 may be configured to filter data packets based on PIDs. In some embodiments, PID filters 255 are created and executed by tuning management processor 210-2. In other embodiments, separate hardware may be used to create and execute such PID filters. Depending on a television channel selected for recording/viewing, a PID filter may be created to filter the video and audio packets associated with the television channel (based on the PID assignments present in PMT 257). For example, if a transponder data stream includes multiple television channels, data packets corresponding to a television channel that is not desired to be stored or displayed by the user, may be ignored by PID filters 255. As such, only data packets corresponding to the one or more television channels desired to be stored and/or displayed may be filtered and passed to either descrambling engine 265 or smart card 260; other data packets may be ignored. For each television channel, a stream of video packets, a stream of audio packets (one or both of the audio programs) and/or a stream of ECM packets may be present, each stream identified by a PID. In some embodiments, a common ECM stream may be used for multiple television channels. Additional data packets corresponding to other information, such as updates to NIT 240, may be appropriately routed by PID filters 255. At a given time, one or multiple PID filters may be executed by tuning management processor 210-2.

Descrambling engine 265 may use the control words output by smart card 260 in order to descramble video and/or audio corresponding to television channels for storage and/or presentation. Video and/or audio data contained in the transponder data stream received by tuners 215 may be scrambled. Video and/or audio data may be descrambled by descrambling engine 265 using a particular control word. Which control word output by smart card 260 to be used for successful descrambling may be indicated by a scramble control identifier present within the data packet containing the scrambled video or audio. Descrambled video and/or audio may be output by descrambling engine 265 to storage medium 225 for storage (in DVR database 245) and/or to audio/video decoder 233 for output to a television or other presentation equipment via television interface 235.

For simplicity, television receiver 200 of FIG. 2 has been reduced to a block diagram; commonly known parts, such as a power supply, have been omitted. Further, some routing between the various modules of television receiver 200 has been illustrated. Such illustrations are for exemplary purposes only. The state of two modules not being directly or indirectly connected does not indicate the modules cannot communicate. Rather, connections between modules of the television receiver 200 are intended only to indicate possible common data routing. It should be understood that the modules of television receiver 200 may be combined into a fewer number of modules or divided into a greater number of modules. Further, the components of television receiver 200 may be part of another device, such as built into a television. Also, while television receiver 200 may be used to receive, store, and present television channels received via a satellite, it should be understood that similar components may be used to receive, store, and present television channels via a cable network.

FIG. 3 illustrates an embodiment 300 of an on-screen interface for making television channel group selections. In embodiment 300, television 310 is displaying an on-screen user interface 305 that allows for selection among multiple television channel groupings. Such an on-screen user interface 305 may be generated by a television receiver and output to a display device, such as television 310, for display. Television receiver 200 of FIG. 2 or some other television receiver may be used to generate on-screen user interface 305.

Each individual group of television channels in the illustrated embodiment is transmitted using a single transponder stream. As such, a particular group of television channels may be concurrently received using a single tuner of the television receiver. For example, group 320-1 contains four television channels. These four television channels may be received concurrently using a single tuner of a television receiver. Therefore, the television receiver may be able to record some or all of the television channels within group 320-1 concurrently.

In illustrated embodiment 300, television channels are assigned to transponder streams based on content categories. Therefore, a first transponder stream may carry mostly or exclusively a particular category of television channels, while a second transponder stream may carry a different category of television programming. As such, groups for recording may be defined based on content categories. This may be useful to a user because a user likely to record a sports television channel may also be likely to desire concurrent recording of another sports-related television channel. Further, assignment to particular groups (and corresponding transponder streams) may vary based on television programming currently being shown on a television channel. For example, a particular television channel may show football on Sunday afternoons, but may broadcast drama on a weekday night.

In some embodiments, each group corresponds to a particular category of content, such as music for group 320-2. However, it should be understood that other grouping methodologies may be used: groupings may be random, based on channel number, alphabetically, based on anticipated or past popularity, based on user voting, based upon previous data that indicates if a first channel is being recorded which other television channels are also likely to be recorded. It should be understood that still other methodologies may also be used.

In illustrated embodiment 300, the user has selected three groups for recording: group 320-1, group 320-5, and group 320-4. Other available groups, such as group 320-3, have not been selected by a user. Each group may require a single tuner to receive and record (and/or present) each television channel within the group concurrently. It should be understood, in some embodiments, a group may require two or more tuners to receive and record (and/or present) each television channel within the group concurrently. It should also be understood that it may be possible for multiple groups to be received by the television receiver as parts of the same transponder stream. For example, each television channel of group 320-1 and group 320-2 may be transmitted as part of the same transponder stream. Accordingly, in such an embodiment, only a single tuner may be required to receive every television channel in group 320-1 and group 320-2.

A user may use a graphical element, such as checkboxes 330, or some other form of indicator to select one or more groups which the user desires to record. In some embodiments, a user may be able to specify particular television channels within the group that the user desires or does not desire to record. For example, referring to group 320-1, checkbox 330-1 has been checked, thus indicating that the user desires to record all four channels within group 320-1. Checkbox 330-2 is unchecked, indicating the user does not desire the television channels of group 320-2 to be recorded. In other embodiments, a user may be able to select individual television channels within group 320-1 that the user desires to record. By each of these television channels being present within group 320-1, the user may be aware that each of these television channels only requires a single tuner for the television channels to be recorded concurrently (thus allowing other tuners to be assigned to receiving other television channels that are transmitted as part of other transponder streams for either recording and/or presentation).

The dates and/or times for the recording of groups of television channels and/or specific television channels within a group may be either user-defined or television service provider-defined. In some embodiments, if a group of television channels is selected, such as group 320-1, the television service provider may define when those particular television channels are recorded. For example, each television channel within a particular group may be recorded during primetime viewing hours, such as from 7 until 10 PM, on a nightly basis. Accordingly, the data that indicates when particular television channels are to be recorded may be transmitted by the television service provider to the television receiver. Thus, the dates and/or times for which a particular group of television channels are recorded may vary according to the dates and/or times selected by the television service provider.

Dates and/or times selected for recording of particular groups may vary based on when programming on the channels within the group is likely to be desired by a user (as decided by an agent at the television service provider). As an example of this, group 320-5 contains television networks that tend to broadcast new television programs during primetime on weekdays between 7 PM and 10 PM. As such, if the user selects group 320-5 for recording and the television service provider is to select the dates and times for recording, group 320-5 may be recorded on weekdays between 7 PM and 10 PM. In contrast, group 320-4 may tend to show television programming desired to be recorded on weekend mornings. As such, the television service provider may provide data to the television receiver such that group 320-4 is recorded only on weekend mornings. Such arrangements may free the user from having to select when groups 320 are to be recorded.

In some embodiments, the user may be able to define when individual groups of television channels are to be recorded. For example, a user may select a group, such as group 320-1, for recording and also specify dates and/or times for which that group of television channels is to be recorded. The user may be permitted to specify a day of the week (e.g., any selection of days, Sunday through Saturday) and periods of time during the selected days of the week for which the television channels are to be recorded. The user may be permitted to specify different dates and/or times for particular television channels within the group and/or different dates and/or times for different groups. In some embodiments, a user is permitted to select as to whether dates and/or times for recording are defined by the television service provider or by the user.

Selection element 340 may permit a user to specify whether or not the user is to define record times. If“no” is selected, times provided by the television service provider may be used for recording. If “yes” is selected, the user may be prompted for recording dates and/or times. When a user has selected “yes,” the default values may be dates/times defined by the television service provider.

The illustrated embodiment 300 of FIG. 3 shows one particular arrangement of how various groups may be presented for selection by a user via a display device by a television receiver. The layout, number of groups, groupings of television channels, and/or graphical elements may vary by embodiment. As such, in other embodiments the presentation of on-screen user interface 305 may vary in content, style, and/or layout.

FIG. 4 illustrates an embodiment 400 of on-screen secondary television channel selections. In embodiment 400, television 310 is displaying an on-screen user interface 405 that allows for selection of a specific television channel for recording. Such an on-screen user interface 405 may be generated by a television receiver and output to a display device, such as television 310, for display. Television receiver 200 of FIG. 2 or some other television receiver may be used to generate on-screen user interface 405.

In the illustrated embodiment 400, a user is using an EPG to select a television program for recording. In the illustrated embodiment, the user has selected television program 410 for recording. This television program appears on a television channel “OO.” At least partially based on the selection of the television program and the television channel, a timer may be created and set at the television receiver such that recording of television channel “OO” begins at 7:30 PM and ends at 10:00 PM, such that the entirety of television program 410 is recorded. The television channel associated with the selected television channel may be referred to as the primary television channel.

In response to the selection of television program 410, on-screen user interface 415 may be caused to be displayed. On-screen user interface 415 permits a user to select one or more secondary television channels for recording during a period of time overlapping the broadcast of television program 410. Each of the secondary television channels from which the user is permitted to select may be transmitted to the television receiver using the same transponder stream as television program 410 (and thus primary television channel “OO”). A secondary television channel refers to a television channel selected for recording on a same transponder stream as the primary channel.

In the illustrated embodiment 400, the user is permitted to select among three television channels also transmitted to the television receiver via the same transponder stream as primary television channel “OO.” The user may be permitted to select one or more of these secondary television channels for recording. Each of these secondary television channels selected via user interface 420 may be received using the same tuner used to receive the primary television channel and television program 410. As such, an additional tuner may not be necessary to record any of the secondary television channels presented in user interface 420 broadcast during the same time period as the primary television channel is being recorded for television program 410. In some embodiments, rather than listing television channels for selection, television programs appearing on those television channels may be listed for selection. As an example, rather than listing “ETV,” a user selection may present to the user for selection whether “Movie: Matches Set the Flame” should be recorded. This movie appears during an overlapping time period on “ETV” as when television program 410 is broadcast on television channel “OO.” Additional television programs overlapping the broadcast time of television program 410 may also be listed.

A user may also be permitted via user interface 430 to indicate whether full television programs are to be recorded. Selection of such an option may prevent only portions of television programs from being recorded via secondary recording selections. For example, television program 410, which was selected for recording by the user, is broadcast from 7:30 PM until 10 PM. Television channel WCVV is also transmitted using the same transponder and is available for selection as a secondary recording by the user. However, during an overlapping period of time as when “OO” is broadcasting television program 410, WCVV is broadcasting television program 412 from 7 PM until 9 PM. As such, if WCVV is only recorded during the time period of television program 410, 30 minutes at the beginning of television program 412 may be omitted from recording. By analyzing locally stored EPG information, the television receiver may modify start and stop times of recordings of secondary television channels selected via user interface 420 such that only full television programs are recorded. Accordingly, for example, if WCVV is to be recorded, recording may begin at 7 PM (using the single tuner). In some embodiments, rather than starting recording early, recording may be started late and thus only television programs 414 and 416 on WCVV may be recorded. Similar adjustments may be made to the end time of recording on a secondary television channel, recording of a secondary television channel may run beyond the end time for recording the primary television channel selected by the user for recording or may cease sooner. If the user indicates that full programs are not be recorded, such as via user interface 430, recording on secondary television channels selected via user interface 420 may occur only during the time period during which the primary selected television program is to be recorded (thus possibly resulting in portions of television programs on the secondary television channels being omitted from recording).

The illustrated embodiment 400 of FIG. 4 shows one particular arrangement of how various groups may be presented for selection by a user via a display device by a television receiver. The layout, number of groups, groupings of television channels, and/or graphical elements may vary by embodiment. As such, in other embodiments the presentation of on-screen user interfaces 405 and 415 may vary in content, style, and/or layout.

FIG. 4B illustrates an embodiment 400B of on-screen television channel selections. In embodiment 400B, a user may be permitted to enable or disable recording of multiple television channels that are transmitted to a television receiver as part of a single transponder stream. A single selection by a user, such as via user interface 455, may permit a user to enable or disable recording of multiple television channels that are transmitted as part of a single transponder stream. Enablement of such multi-channel recording may involve each of the multiple television channels being received over overlapping periods of time using a single tuner of the television receiver for receiving the multiple television channels. For example, four television channels may be received as part of a single transponder stream by a single tuner of the television receiver over a same period of time, such as from 7 PM until 10 PM. The specific television channels and the time periods at which the television channels are recorded may be set by the television service provider and transmitted by the television service provider to the television receiver. For example, a user may enable recording of multi-channel recording using a single selection via user interface 455. The time periods and/or channels that are recorded may be determined based on data received by the television receiver from the television service provider.

In some embodiments, if a user enables such multi-channel recording, additional options may be presented to the user, such as via user interface 475. A user may be permitted to specify which days of the week and/or which channels (from a predefined group of television channels) are to be recorded. Each television channel listed in user interface 475 may be transmitted to the television receiver as part of a single transponder stream (such that a single tuner of the television receiver may be used to receive each of the television channels over a same period of time). Without requiring the use of an additional tuner, a user may select as many or as few television channels from user interface 475 for recording. These television channels may be recording during overlapping periods of time using a single tuner of the television receiver.

The user may also be able to specify particular days of the week for recording. For example, a user may not want to record particular days of the week because the user does not find any television programming appearing on the selected television channels on such days to be worth recording for future viewing. A user may also be able to define particular television programs to record or not record. For example, a user may be able to specify (e.g., select from a list) a title of a television program that is never to be recorded. In some embodiments, a user may be able to specify that reruns (i.e., television programs that have been previously broadcast by the television channel) are not to be recorded. Whether a television program is a rerun may be based on determining if an “original broadcast date” stored in the EPG information for a television program matches a current date: if the dates match, the television program may not be a rerun, if the original broadcast date is some day in the past, the television program may be a rerun. Based on whether multi-channel recording is enabled by a user, the days of the week selected by a user, and/or the channels that are part of the transponder stream selected by the user, timers may be configured to record the selected television programming. The specific time periods for each television channel (e.g., from 7-10 PM) may be determined by the television service provider and transmitted to the television receiver. The television receiver may receive from the television service provider timers for each day and channel. Timers for days and/or channels that are not selected for recording by the user may be ignored by the television receiver. For example, in illustrated embodiment 400B, timers related to recording on Saturdays may be ignored. Regardless of the number of television channels selected (from a list of television channels defined by the television service provider) and/or which days of the week (or the number of days of week) selected, only a single tuner may be needed by the television receiver to receive each of the television channels, even if recording occurs on each of the television channels during overlapping periods of time.

The illustrated embodiment 400B of FIG. 4B shows one particular arrangement of how various groups may be presented for selection by a user via a display device by a television receiver. The layout, number of groups, groupings of television channels, and/or graphical elements may vary by embodiment. As such, in other embodiments the presentation of on-screen user interfaces 450 and 470 may vary in content, style, and/or layout.

Various methods may be performed using the previously detailed systems and on-screen interfaces. FIG. 5 illustrates an embodiment of a method 500 for recording multiple television channels concurrently. Method 500 may be performed using satellite television distribution system 100 of FIG. 1 or some other form of television distribution system (which may be cable-based). Method 500 may be performed using a television receiver, such as television receiver 200 of FIG. 2. Each step of method 500 may be performed by a television receiver. In addition to having components similar to television receiver 200 of FIG. 2, computerized components, such as the components of computer system 900 of FIG. 9 may be incorporated as part of the television receiver that performs method 500. Means for performing method 500 include one or more instances of some or all components of television receiver 200 of FIG. 2 and/or computer system 900 of FIG. 9.

At step 510, an indication of television channel groupings may be received by the television receiver. A television service provider may transmit an indication of various television channels which are transmitted to the television receiver via a single transponder stream and, thus, can be received concurrently using a single tuner of the television receiver. Referring to satellite television distribution system 100, such an indication of the television channel groupings may be transmitted to television receiver 150 via satellite or may use some alternate communication route, such as via network 190. It should be understood that in other embodiments of method 500, some other form of communication between a television service provider and a television receiver may be used, such as a cable television network. Such indications of the groups of television channels may be stored by the television receiver, such as by group database 244 of television receiver 200 of FIG. 2.

In some embodiments, rather than receiving an indication of groups of television channels and storing such an indication in a grouping database, a television receiver may be able to analyze locally stored data to determine which television channels are transmitted to the television receiver on a particular transponder and can be received concurrently using a single tuner. At step 512, such analysis may include analyzing data present in an NIT, PMT, and/or some other data storage arrangement that is stored by the television receiver that indicates frequencies or satellites and transponders to which particular television channels are assigned. As such, by determining television channels that are associated with a common frequency or indicate a common satellite and transponder, the television receiver may be able to determine which television channels can be recorded concurrently using a single tuner to receive a single transponder stream at step 514. Further, decryption of control words and/or descrambling using control words may need to be considered as to which television channels can be recorded over the same period of time. For example, it may be necessary for the same control word to be used for descrambling across each television channel within a group. In some embodiments, the results of such a determination may be stored in a group database, such as group database 244 of television receiver 200.

At step 520, a graphical user interface (also referred to as an on-screen user interface) may be presented to a user that indicates various groups of television channels for selection. As an example, embodiment 300 of FIG. 3 illustrates such a graphical user interface. Each group may contain multiple television channels. Each of the television channels contained within the group may be transmitted using a single transponder stream. As such, a single tuner may be used to receive (for recording and/or presentation) each television channel within a group concurrently. Via a user input device, a user may be permitted to select one or more groups of television channels for recording. It may be necessary to determine whether sufficient tuners are available at the television receiver to record the groups selected by the user. For instance, if two or more groups are selected and at least two of the groups are to be recorded concurrently, the television receiver may need to have two available tuners to assign two tuners to record the two groups. For example, a tuner may be reserved by the television receiver to allow the user to watch television channels live. As such, to select two groups, a television receiver may be required to have at least three tuners.

At step 530, selections of one or more groups from the user may be received by the television receiver. In some embodiments, the user may be restricted to selecting a particular number of groups. For example, a user may only be permitted to select a single group for recording. In other embodiments, a user may be able to select 2, 3, 4, 5, or more groups for recording. In some embodiments, a television service provider assigns television channels to particular transponder streams based on categories or some other factor, such as popularity. As such, particular groups of television channels may share characteristics, for example each television channel within a particular group may be devoted to sports, news, or music to name only three examples of categories. Indications of the selected groups of television channels may be stored by the television receiver. In some embodiments, the user is permitted to select particular television channels within a group without selecting the entire group. As such, television channels which are not desired by the user may be ignored and never recorded within a particular group.

At step 540, indications of the dates and/or times which the selected groups of television channels are to be recorded may be received. In some embodiments, these dates and times may be received from a television service provider, such as via a satellite television distribution system. In various embodiments, the television service provider may define when particular television channels and/or particular groups of television channels are to be recorded. In other embodiments, the indications of date and/or times at which groups of television channels are to be recorded may be received from the user of the television receiver. In some embodiments, the user can provide input indicating whether the dates and times are to be set by the user or are to be set by the television service provider. In some embodiments, the television service provider may provide default times and/or dates and the user may be permitted to modify those default times and/or dates. The indications of the dates and/or times at which the selected groups of television channels are to be recorded may be stored by the television receiver.

At step 550, timers for recording of each television channel in the selected groups of television channels may be set for the dates and/or times received at step 540. These timers may be stored by the television receiver. After these timers have been set, it may be permissible for a user to modify the timers and/or cancel recording for a particular date and/or times regardless of whether the dates and/or times were initially specified by the user or by the television service provider.

At step 560, television channels may be recorded according to the timers set at step 550. Multiple television channels present within a group selected by the user may be received for recording using a single tuner of the television receiver. As such, if a user selected a group of television channels for recording at step 530 and the indications of the dates and/or times received at step 540 indicate that each of those television channels are to be recorded concurrently, only a single television tuner may be used to concurrently receive each television channel present within the group. For each television channel recorded at step 560, a separate file may be created on a storage medium of the television receiver. In some embodiments, individual files are created for each television program that is recorded. The start and stop times of particular television programs may be based on EPG data, such as data from EPG database 230 of FIG. 2.

FIG. 6 illustrates another embodiment of a method for recording multiple television channels concurrently. Method 600 may be performed using satellite television distribution system 100 of FIG. 1 or some other form of television distribution system (which may be cable-based). Method 600 may be performed using a television receiver, such as television receiver 200 of FIG. 2. Each step of method 600 may be performed by a television receiver. In addition to having components similar to television receiver 200 of FIG. 2, computerized components, such as the components of computer system 900 of FIG. 9, may be incorporated as part of the television receiver that performs method 600. Means for performing method 600 include one or more instances of some or all components of television receiver 200 of FIG. 2 and/or computer system 900 of FIG. 9. A television receiver that performs method 500 may also perform method 600.

At step 610, an indication of television channel groupings may be received by the television receiver. A television service provider may transmit an indication of various television channels which are transmitted to the television receiver via a single transponder stream and, thus, can be received concurrently using a single tuner of the television receiver. Referring to satellite television distribution system 100, such an indication of the television channel groupings may be transmitted to television receiver 150 via satellite or may use some alternate communication route, such as via network 190. It should be understood that in other embodiments of method 600, some other form of communication between a television service provider and a television receiver may be used, such as a cable television network. Such indications of the groups of television channels may be stored by the television receiver, such as by group database 244 of television receiver 200 of FIG. 2.

At step 620, a selection of a television program to record may be received from a user. The selection may be made by the user via an EPG interface. For example, referring to FIG. 4, and onscreen EPG may be presented that allows a user to select a particular television program broadcast by a television channel over a time period.

At step 630, multiple other television channels which are broadcast to the television receiver using a same transponder and transponder stream as the television program selected for recording may be determined. These multiple other television channels may be determined based on the indication of groups of television channels received by the television receiver at step 610, such as by analyzing a grouping database. In other embodiments, rather than receiving an indication of groups of television channels and storing such an indication in a grouping database, a television receiver may be able to analyze locally stored data to determine which television channels are transmitted to the television receiver via a particular transponder and can be received concurrently using a single tuner. Such analysis may include analyzing data present in an NIT, PMT, and/or some other data storage arrangement that is stored by the television receiver that indicates frequencies or satellites and transponders to which particular television channels are assigned. By determining television channels that are associated with a common frequency or indicate a common transponder of a same satellite, the television receiver may be able to determine which television channels can be recorded concurrently using a single tuner to receive a single transponder stream at step 630. In some embodiments, the results of such a determination may be stored in a grouping database, such as group database 244 of television receiver 200.

At step 640, an onscreen interface may be presented to a user that identifies the plurality of television channels determined at step 630 to be broadcast on the same transponder as a television program. As such, at step 640, the user may be provided with an opportunity to select among the plurality of television channels to identify which additional television channels are to be recorded by the television receiver. Each of these additional television channels to be recorded may be received by the television receiver using the same tuner used to receive the television program selected at step 620. At step 650, a selection of one or more television channels that are transmitted to the television receiver via the same transponder stream may be received.

At step 660, timers for recording of each user selection, including the television program identified at step 620 and the television channels indicated by the selections received at step 650, may be set by the television receiver. Each timer may include a television channel, a start time, and an end time. The start and end times of timers for the television channels indicated by the selections of step 650 may be adjusted according to method 700 of FIG. 7 such that recording of complete television programs is ensured. In some embodiments, the start and end time of timers of the television channels indicated by the selections of step 650 are set to match the start and end time of the time for the television program identified at step 620 (regardless of whether recording of one or more television programs will be truncated).

At step 670, television channels may be recorded according to the timers set at step 660. Each of the television channels/programs selected for recording in method 600 may require only a single tuner be used for receiving the television programming. For each television channel recorded at step 670, a separate file may be created on a storage medium of the television receiver. In some embodiments, files are created for each television program that is recorded. The start and stop times of particular television programs may be based on EPG data, such as data from EPG database 230 of FIG. 2.

When embodiments of method 600 are performed, it may be desired to ensure that entire television programs recorded such that beginnings and/or endings of television programs are not truncated from recording. As an example, referring to FIG. 4, a user has selected television program 410 for recording. This television program begins at 7:30 PM and ends at 10 PM. Therefore a timer is set by the television receiver to record television program 410 that has a start time of 7:30 PM and an end time of 10:00 PM. However, other television channels transmitted to the television receiver via the same transponder and selected for recording by the user may not have the same start and/or end times. For example, television program 412 on WCVV starts at 7 PM and ends at 9 PM. As such, if the user has indicated that WCVV is to also be recorded during the recording of television program 410, the timing of recording of television channel WCVV may be adjusted such that television program 412 is recorded in its entirety or is omitted from being recorded (rather than having recording start 30 minutes into television program 412).

FIG. 7 illustrates an embodiment of a method 700 for using electronic programming guide information to ensure entire television programs are recorded. Method 700 may be performed using satellite television distribution system 100 of FIG. 1 or some other form of television distribution system (which may be cable-based). Method 700 may be performed using a television receiver, such as television receiver 200 of FIG. 2. Each step of method 700 may be performed by a television receiver. In addition to having components similar to television receiver 200 of FIG. 2, computerized components, such as the components of computer system 900 of FIG. 9 may be incorporated as part of the television receiver that performs method 600. Means for performing method 700 include one or more instances of some or all components of television receiver 200 of FIG. 2 and/or computer system 900 of FIG. 9. Method 700 may be performed in conjunction with method 500 of FIG. 5 and/or method 600 of FIG. 6 to ensure entire television programs are recorded. For example, referring to method 500, at least some steps of method 700 may be performed as part of step 550. As another example, referring to method 600, method 700 may be performed as part of step 660.

At step 710, a timer may be set for a first television program. This timer may indicate a start time, an end time, a date, and a television channel. Referring to method 600, this timer may be set for the television program indicated by the selection of step 620 (that is, the primary television program selected for recording by the user). In embodiments of method 700 as applied to method 500, rather than setting a first timer for television program at step 710, a time period indicated for recording as received from a user or from a television service provider may be accessed.

At step 720, EPG data received and stored by the television receiver may be analyzed to determine start and end times for television programs appearing on the television channels that are to be recorded. Referring to method 600, each secondary television channel selected for recording at step 650 may have associated EPG data retrieved and/or analyzed.

At step 730, for each selected television channel to be recorded (such as television channels indicated to be recorded at step 650), it may be determined whether a television program begins at the start time of the first record timer or at an earlier time. For example, referring to embodiment 400 of FIG. 4, a timer for television program 410 begins at 7:30 PM. On ETV, a television channel selected for recording, a television program begins at a same time as the start time for the timer. However, referring to WCVV, the television program broadcast at 7:30 begins at 7:00 PM.

If, at step 730, for a secondary television channel to be recorded, it is determined the start time of a scheduled television program on the secondary television channel matches the start time of the timer set at step 710 for the television program on the primary television channel, method 700 may proceed to step 740. At step 740, a start time for a record timer for the secondary television channel to be recorded may be set to match the start time for the record timer of the primary television channel.

If, at step 730, for a secondary television channel to be recorded, it is determined that a scheduled television program on the secondary television channel will be in progress (according to stored EPG information) at the start time of the timer set at step 710 for the television program on the primary television channel, method 700 may proceed to step 745. At step 745, an earlier start time may be set for the record timer for the secondary television channel to match a start time of the television program that is scheduled to be in progress at the start time of the timer set at step 710. The same tuner that will record the first television program may be used to receive each secondary television channel. In some embodiments, rather than setting an earlier start time, a later start time may be set for the record timer for the secondary television channel such that recording of the entire television program that is scheduled to be in progress at the start time of the timer set at step 710 is omitted (thus resulting in a start time for the timer for the secondary television channel being set that is later than the start time of the timer set at step 710). Still, the same tuner that records the first television channel will be used for receiving each secondary television channel.

After step 740 or step 745, step 750 may be performed. At step 750, for each selected television channel to be recorded (such as television channels indicated to be recorded at step 650), it may be determined whether a television program ends at the end time of the first record timer or at a later time. For example, referring to embodiment 400 of FIG. 4 a timer for television program 410 ends at 10:00 PM. On ETV, a television channel selected for recording, a television program (“Golf News”) ends at a same time as the end time for the timer. However, referring to “MGN”, the television program broadcast at 9:30 may go until 10:30 PM.

If, at step 750, for a secondary television channel to be recorded, it is determined the end time of a scheduled television program on the secondary television channel matches the end time of the timer set at step 710 for the television program on the primary television channel, method 700 may proceed to step 760. At step 760, an end time for a record timer for the secondary television channel to be recorded may be set to match the end time for the record timer of the primary television channel.

If, at step 750, for a secondary television channel to be recorded, it is determined that a scheduled television program on the secondary television channel will be in progress according to stored EPG information at the end time of the timer set at step 710 for the television program on the primary television channel, method 700 may proceed to step 765. At step 765, a later end time may be set for the record timer for the secondary television channel to match an end time of the television program that is scheduled to be in progress at the end time of the timer set at step 710. In some embodiments, rather than setting a later end time, a time may be set for the record timer for the secondary television channel such that recording of the entire television program that is scheduled to be in progress at the end time of the timer set at step 710 is omitted (thus resulting in an end time for the timer for the secondary television channel being set that is earlier than the end time of the timer set at step 710).

Steps 730 through 765 of method 700 may be performed for each secondary television channel to be recorded. The previous description of method 700 focuses on performing steps of method 700 in conjunction with method 600. However, method 700 may also be performed in conjunction with method 500 of FIG. 5. If method 700 is performed in conjunction with method 500, rather than setting a first timer at step 710 for a primary channel, method 700 may begin at step 720 with EPG data being analyzed for each television program to be recorded over a period of time defined by either the television service provider or by a user. The start and end times for recording may, by default, be set for the start of the period of time and the end of the period of time, respectively, defined by the television service provider or user. Steps 720 through 765 may be used to adjust the start time and end time of the recording time period defined by the user or the television service provider such that only complete television programs are recorded.

FIG. 8 illustrates an embodiment of a method 800 for recording multiple television channels based on user input. Method 800 may be performed using satellite television distribution system 100 of FIG. 1 or some other form of television distribution system (which may be cable-based). Method 800 may be performed using a television receiver, such as television receiver 200 of FIG. 2. Each step of method 800 may be performed by a television receiver. In addition to having components similar to television receiver 200 of FIG. 2, computerized components, such as the components of computer system 900 of FIG. 9 may be incorporated as part of the television receiver that performs method 800. Means for performing method 800 include one or more instances of some or all components of television receiver 200 of FIG. 2 and/or computer system 900 of FIG. 9. Method 800 may include the use of user interfaces similar to presented in FIG. 4B.

At step 810, an indication of a group of television channels that are transmitted as part of a same transponder stream may be received by the television receiver. A television service provider may transmit an indication of various television channels which are transmitted to the television receiver via a single transponder stream and, thus, can be received during a same time period (econcurrently) using a single tuner of the television receiver. Referring to satellite television distribution system 100, such an indication of the television channel groupings may be transmitted to television receiver 150 via satellite or may use some alternate communication route, such as via network 190. It should be understood that in other embodiments of method 800, some other form of communication between a television service provider and a television receiver may be used, such as a cable television network. As such, a transponder stream may refer to a stream of television channels transmitted using a single RF channel of the cable network. Such indications of the groups of television channels may be stored by the television receiver, such as by group database 244 of television receiver 200 of FIG. 2.

At step 820, a graphical user interface may be presented to the user by the television receiver (e.g., via a display device) that permits the user to enable or disable multiple channel recording. A single user input may either enable or disable recording of multiple television channels, possibly over an overlapping time period (e.g., daily from 7-10 PM on each of the television channels). Which television channels and the date/time periods over which the television channels are recorded may be defined, at least as a default, by the television service provider. Each of the eligible television channels may be transmitted as part of a particular transponder stream.

At step 825, it may be determined by the television receiver whether the user has selected to enable or disable recording of the multiple channels received using a single tuner of the television receiver. If the user has provided input that disables recording of the multiple channels, method 800 may proceed to step 827. At step 827, no timers may be set for future recording of the multiple channels (e.g., timer data received from the television service provider may be ignored or stored but disabled). Further, any timers previously set for future recording of the multiple channels may be deleted or disabled. If the user has provided input that enables recording of the multiple channels, method 800 may proceed to step 830.

In some embodiments, the television channels, dates, and time periods for recording are determined by the television service provider. As such, following step 825, method 800 may proceed to step 850 in which timers are set according to dates, time periods, and/or television channels that are specified by the television service provider via data that is transmitted by the television service provider to television receiver. In other embodiments, the user may be able to modify which television channels and/or on which dates television channels are recorded. At step 830, another graphical user interface (or an option as part of the same user interface) may be provided that requests the user specify particular days on which recording of the multiple channels is to occur. The user may have the opportunity to specify any combination of days of the week for recording. The user may be able specify that every day of the week is recorded. In some embodiments, the user may provide input for each day of the week which indicates that recording of the multiple channels is enabled or disabled. The time periods on the individual days for recording may be specified by the television service provider (or, in some embodiments, a user may be permitted to indicate the desired periods of time for recording of the television channels). Each time period may include times during which multiple television programs are broadcast. For example, during a time period of 7:00 PM-10:00 PM a particular television channel may broadcast three to six television programs. At step 835, user input may be received by the television receiver that indicates which days of the week the multiple television channels are to be recorded, during which recording, a single tuner for reception of the television channels is used by the television receiver.

At step 840, a user interface may be provided that requests the user specify particular television channels of the multiple channels is to occur. The user may have the opportunity to specify any combination of television channels from the predefined group of television channels. The group of television channels may include only television channels that are transmitted as part of a particular transponder stream. The television channels which are part of the group may have been indicated to the television receiver at step 810. Since the television channels are received as part of the same transponder stream, regardless of the combination of television channels selected by the user, the television channels may be received over at least an overlapping period of time using a single tuner of the television receiver. At step 845, user input may be received by the television receiver that indicates which television channels of the multiple television channels are to be recorded, using a single tuner for reception of the selected television channels.

At step 850, timers may be set for recording of the television channels. Timers may only be set at the set top box for television channels of the multiple television channels selected by the user and only on days selected by the user. The specific time periods for each day may be set by the television service provider. The time periods at which the television channels are recorded may either partially or fully overlap. By the time periods at least partially overlapping, an overlapping time period during which each of the television channels is to be recorded may be defined. For example, each of the television channels may be recorded from 7 PM until 10 PM nightly. The timer set at step 850 may result in channel specific files being recorded for each television channel selected by the user, wherein each channel specific file contains multiple television programs broadcast during the time period recorded by the television receiver. Data used to create timers may be received from the television service provider for recording of each television channel of the multiple television channels for each day of the week. Data for timers related to television channels not selected by the user and/or data for timers on days not selected by the user may be ignored (or stored but disabled), such that timers are only set on the television channels and/or days selected by the user. If, at some point, the user modifies the television channels and/or days selected for recording, one or more corresponding disabled timers may be enabled for recording. At step 855, the television receiver may record the television channels in accordance with the timers set at step 850. Once recorded based on the timers, the recordings of the television channels may be available for playback and output to a display device.

FIG. 9 illustrates an embodiment of a computer system 900. A computer system as illustrated in FIG. 9 may be incorporated as part of the previously described computerized devices. For example, computer system 900 can represent some of the components of the television receivers and/or television service provider systems discussed in this application. FIG. 9 provides a schematic illustration of one embodiment of a computer system 900 that can perform various steps of the methods described herein. It should be noted that FIG. 9 is meant only to provide a generalized illustration of various components, any or all of which may be utilized as appropriate. FIG. 9, therefore, broadly illustrates how individual system elements may be implemented in a relatively separated or relatively more integrated manner.

The computer system 900 is shown comprising hardware elements that can be electrically coupled via a bus 905 (or may otherwise be in communication, as appropriate). The hardware elements may include one or more processors 910, including without limitation one or more general-purpose processors and/or one or more special-purpose processors (such as digital signal processing chips, graphics acceleration processors, and/or the like); one or more input devices 915, which can include without limitation a mouse, a keyboard, and/or the like; and one or more output devices 920, which can include without limitation a display device, a printer, and/or the like.

The computer system 900 may further include (and/or be in communication with) one or more non-transitory storage devices 925, which can comprise, without limitation, local and/or network accessible storage, and/or can include, without limitation, a disk drive, a drive array, an optical storage device, a solid-state storage device, such as a random access memory (“RAM”), and/or a read-only memory (“ROM”), which can be programmable, flash-updateable and/or the like. Such storage devices may be configured to implement any appropriate data stores, including without limitation, various file systems, database structures, and/or the like.

The computer system 900 might also include a communications subsystem 930, which can include without limitation a modem, a network card (wireless or wired), an infrared communication device, a wireless communication device, and/or a chipset (such as a Bluetooth™ device, an 802.11 device, a WiFi device, a WiMax device, cellular communication facilities, etc.), and/or the like. The communications subsystem 930 may permit data to be exchanged with a network (such as the network described below, to name one example), other computer systems, and/or any other devices described herein. In many embodiments, the computer system 900 will further comprise a working memory 935, which can include a RAM or ROM device, as described above.

The computer system 900 also can comprise software elements, shown as being currently located within the working memory 935, including an operating system 940, device drivers, executable libraries, and/or other code, such as one or more application programs 945, which may comprise computer programs provided by various embodiments, and/or may be designed to implement methods, and/or configure systems, provided by other embodiments, as described herein. Merely by way of example, one or more procedures described with respect to the method(s) discussed above might be implemented as code and/or instructions executable by a computer (and/or a processor within a computer); in an aspect, then, such code and/or instructions can be used to configure and/or adapt a general purpose computer (or other device) to perform one or more operations in accordance with the described methods.

A set of these instructions and/or code might be stored on a non-transitory computer-readable storage medium, such as the non-transitory storage device(s) 925 described above. In some cases, the storage medium might be incorporated within a computer system, such as computer system 900. In other embodiments, the storage medium might be separate from a computer system (e.g., a removable medium, such as a compact disc), and/or provided in an installation package, such that the storage medium can be used to program, configure, and/or adapt a general purpose computer with the instructions/code stored thereon. These instructions might take the form of executable code, which is executable by the computer system 900 and/or might take the form of source and/or installable code, which, upon compilation and/or installation on the computer system 900 (e.g., using any of a variety of generally available compilers, installation programs, compression/decompression utilities, etc.), then takes the form of executable code.

It will be apparent to those skilled in the art that substantial variations may be made in accordance with specific requirements. For example, customized hardware might also be used, and/or particular elements might be implemented in hardware, software (including portable software, such as applets, etc.), or both. Further, connection to other computing devices such as network input/output devices may be employed.

As mentioned above, in one aspect, some embodiments may employ a computer system (such as the computer system 900) to perform methods in accordance with various embodiments of the invention. According to a set of embodiments, some or all of the procedures of such methods are performed by the computer system 900 in response to processor 910 executing one or more sequences of one or more instructions (which might be incorporated into the operating system 940 and/or other code, such as an application program 945) contained in the working memory 935. Such instructions may be read into the working memory 935 from another computer-readable medium, such as one or more of the non-transitory storage device(s) 925. Merely by way of example, execution of the sequences of instructions contained in the working memory 935 might cause the processor(s) 910 to perform one or more procedures of the methods described herein.

The terms “machine-readable medium” and “computer-readable medium,” as used herein, refer to any medium that participates in providing data that causes a machine to operate in a specific fashion. In an embodiment implemented using the computer system 900, various computer-readable media might be involved in providing instructions/code to processor(s) 910 for execution and/or might be used to store and/or carry such instructions/code. In many implementations, a computer-readable medium is a physical and/or tangible storage medium. Such a medium may take the form of a non-volatile media or volatile media. Non-volatile media include, for example, optical and/or magnetic disks, such as the non-transitory storage device(s) 925. Volatile media include, without limitation, dynamic memory, such as the working memory 935.

Common forms of physical and/or tangible computer-readable media include, for example, a floppy disk, a flexible disk, hard disk, magnetic tape, or any other magnetic medium, a CD-ROM, any other optical medium, any other physical medium with patterns of marks, a RAM, a PROM, EPROM, a FLASH-EPROM, any other memory chip or cartridge, or any other medium from which a computer can read instructions and/or code.

Various forms of computer-readable media may be involved in carrying one or more sequences of one or more instructions to the processor(s) 910 for execution. Merely by way of example, the instructions may initially be carried on a magnetic disk and/or optical disc of a remote computer. A remote computer might load the instructions into its dynamic memory and send the instructions as signals over a transmission medium to be received and/or executed by the computer system 900.

The communications subsystem 930 (and/or components thereof) generally will receive signals, and the bus 905 then might carry the signals (and/or the data, instructions, etc. carried by the signals) to the working memory 935, from which the processor(s) 910 retrieves and executes the instructions. The instructions received by the working memory 935 may optionally be stored on a non-transitory storage device 925 either before or after execution by the processor(s) 910.

It should further be understood that the components of computer system 900 can be distributed across a network. For example, some processing may be performed in one location using a first processor while other processing may be performed by another processor remote from the first processor. Other components of computer system 900 may be similarly distributed.

The methods, systems, and devices discussed above are examples. Various configurations may omit, substitute, or add various procedures or components as appropriate. For instance, in alternative configurations, the methods may be performed in an order different from that described, and/or various stages may be added, omitted, and/or combined. Also, features described with respect to certain configurations may be combined in various other configurations. Different aspects and elements of the configurations may be combined in a similar manner. Also, technology evolves and, thus, many of the elements are examples and do not limit the scope of the disclosure or claims.

Specific details are given in the description to provide a thorough understanding of example configurations (including implementations). However, configurations may be practiced without these specific details. For example, well-known circuits, processes, algorithms, structures, and techniques have been shown without unnecessary detail in order to avoid obscuring the configurations. This description provides example configurations only, and does not limit the scope, applicability, or configurations of the claims. Rather, the preceding description of the configurations will provide those skilled in the art with an enabling description for implementing described techniques. Various changes may be made in the function and arrangement of elements without departing from the spirit or scope of the disclosure.

Also, configurations may be described as a process which is depicted as a flow diagram or block diagram. Although each may describe the operations as a sequential process, many of the operations can be performed in parallel or concurrently. In addition, the order of the operations may be rearranged. A process may have additional steps not included in the figure. Furthermore, examples of the methods may be implemented by hardware, software, firmware, middleware, microcode, hardware description languages, or any combination thereof. When implemented in software, firmware, middleware, or microcode, the program code or code segments to perform the necessary tasks may be stored in a non-transitory computer-readable medium such as a storage medium. Processors may perform the described tasks.

Having described several example configurations, various modifications, alternative constructions, and equivalents may be used without departing from the spirit of the disclosure. For example, the above elements may be components of a larger system, wherein other rules may take precedence over or otherwise modify the application of the invention. Also, a number of steps may be undertaken before, during, or after the above elements are considered. Accordingly, the above description does not bind the scope of the claims.
